摘　　要：以滇西北香格里拉县这一生态敏感地区为研究区,利用2006～2009年野外实测样方数据,对其云冷杉林、高山松林、栎类林、云南松林4个主要森林生态系统的生物量、碳储量和碳密度进行估算.结果表明,其总生物量为13 745.23万t,总碳储量为6 762.13万t,平均碳密度为88.9 t/hm2.其中云冷杉林生物量最大,占全县总生物量的50.3%,其碳密度也最高,为113.31 t/hm2.Taking the ecologically sensitive area of Shangri-La County in northwest Yunnan as the study area, by using the plot data of field survey from 2006 to 2009, to estimate its biomass, carbon stocks and carbon density of the four main forest ecosystem. The results show that： the total biomass is 137 452 300 t; total carbon reserve is 67, 621, 300t; the average carbon density is 88.9 t/hm2. The largest forest biomass is Abies georgei that occupies 50.3% in total and it has the highest carbon density of 113.31t/hm2 as well. The average carbon density in the four types of forests ecosystem in Shangri-La is close to the estimation of carbon density in domestic and foreign forest.
